Patented July 29, 1947 UNITED STATES ROLLER AND OTHER SKATES StanleyGuttridge, Wanstead, London, England Application September 5, 1945,Serial No. 614,455 In Great Britain September 20, 1944 4 Claims.

This invention relates to roller and other skates and has for its objectto provide an improved construction which enables the roller or bladepart of the skate to be readily detachably secured to the skate plateand to be insulated therefrom by suitable shock absorbing means. Theinvention also provides simple means to enable the rollers to pivot forsteering.

According to this invention the rollers of a roller skate are mountedupon a separate chassis which is readily detachably secured to the skateplate and is insulated therefrom by shock absorbing means. The chassismay be detached and a blade substituted and secured by similar means,for ice skating.

According to a preferred form of the invention the said securing meanscomprises apertured lugs projecting downwardly from the underside of theskate plate and which are adapted to receive pins projecting upwardlyfrom said detachable roller T 2 skate chassis or said ice blade.

According to one embodiment the upper ends of said pins are threaded toreceive nuts accommodated in recesses in the upper face of the skateplate and which bear upon rubber buffers provided between said lugs andthe nuts, whilst according to another embodiment the upper ends of saidpins are each formed with recesses adapted to receive the end of aspring loaded locking pin located in the wall of each of said lugs.

The said shock absorbing means comprises rubber buffers provided betweensaid lugs and parts on the roller skate chassis or the ice blade adaptedto fit in slots at the bottom of said lugs.

The wheels of the roller skate may be mounted on axles adapted to pivotabout steering pins on the chassis and may be provided with steeringdampers operating by cam action and adjusting means may be incorporatedfor alignment of the front and rear wheels.

In order that the invention may be clearly understood and readilycarried into effect, reference will now be made to the accompanyingdrawings which illustrate various embodiments of the invention by way ofexample. On the drawings:

Fig. 1 is a part sectional side elevation of the invention as applied toa roller skate.

Fig. 2 is an inverted plan view showing the bogie at the forward or toepart of the skate.

Fig. 3 is a side elevation showing the skate plate of Fig. 1 fitted withan ice blade.

Fig. 4 is a cross-section showing an alternative form of quick releasefor enabling an ice blade to be substituted for a roller skate chassisor vice-versa.

Fig. 5 is a side elevation to a larger scale of a wheel carrying axlehousing.

Fig. '6 is a section taken on the line VI-VI of Fig. 5 but including thebogie wheels.

Fig. '7 is an exploded View showing separately the various parts of thewheel carrying axle housing.

Referring to the drawings the skate plate I is shaped to correspondsubstantially to the outline of the boot or shoe to which it is to besecured and it may be provided with'holes 2 for fixing screws atsuitable positions, in any well known manner. The underside of the plateI may be provided with suitable stiffening ribs 3 and downwardlyprojecting lugs 4 are provided to support the detachable chassis. Theskate plate I may comprise a light aluminum or alloy casting with theribs or lugs 3 formed as integral parts thereof.

The chassis comprises a longitudinal metal rod 5 adapted to be securedin the downwardly projecting lugs 4 of the skate plate I and is providedat each end with upwardly directed steering pins 6 about which thewheels 1 may turn for steering purposes. The chassis member ispreferably square at its two ends 8 to engage in vertical slots 9 in thelugs 4 on the skate plate I so that it may move up and down therein andthe two ends are connected together by the steel rod 5 of reduced sizeso as to keep down the weight. The chassis is located and held in thelugs 4 by upwardly projecting pins I0 (see Fig. 1) which pass throughthe lugs 4 and are secured by recessed nuts II screwed onto their upperends from the upper face of the skate plate I. Suitable resilient shockabsorbing means such as rubber buffers I2 are provided between the lugs4 and the chassis and also between the lugs 4 and the nuts II on thesecuring pins on the chassis. The recessed nuts II enable the shockabsorbing means I2 to be suitably adjusted. When these nuts II areremoved the complete chassis may be readily removed from the skate plateI and if desired a suitably shaped ice blade I3 (see Fig. 3) may besubstituted and secured in a similar manner.

Instead of locking the chassis to the skate plate I by means of recessednuts II screwed onto the upper ends of the pins Ill, the latter may, asshown by Fig. 4 each be formed with a recess I4 into which is adapted tosnap the inner end of a locking pin I5 connected to the free end of aleaf spring I6 secured at its other end to the lug 4. Thus bywithdrawing the inner end of the locking pin I5 clear of the recess I4,for which purpose the pin may be provided with a knurled head H, thechassis of say a roller skate may be removed and an ice blade 13 fittedin place thereof or vice-versa. This modification provides a quickrelease means which does not involve the need for unscrewing the nuts Hpreviously referred to. The upper end of each pin I is in this casepreferably formed with a tapered part Illa to press the locking pins 15outwardly automatically when a roller skate chassis or an ice blade I3 ibeing fitted to the skate plate I to avoid moving the pin 15 manually,the latter snapping back into a locking position when the recess I4 isbrought into registration with the inner end of the pin [5.

The front and rear steering pins 6 at the ends of the chassis arepreferably inclined to a suitable extent in a forward and rearwarddirection respectively and are gripped in'split extensions 8a of thesquared portions 8 and locked therein by locking screws 81). On eachsteering pin 6 is mounted a bogie comprising a wheel carrying axlehousing l8 and axle 19 for a pair of Wheels 1' and damping means 23 forcontrolling the steering of the bogie. The housing 18 is provided with abearing to fit on the upwardly extending steering pin 6 and is securedin position by a washer 29 and a pin 2| passed transversely through theupper projecting end of the steering pin 6. The axle housing is slottedtransversely at 22 in a plane approximately at right angles to the axisof the steering pin 6 and in this slot is located a steering damperplate 23. The damper plate 23 is slotted at 26 to fit round the steeringpin 6 and a transverse recess 25 is formed in the steering pin in linewith the damper plate 23 so that they may interlock and the centreportion of the damper plate will engage against the flat base of therecess 25 in the steering pin 6. The damper plate 23 is pressedresiliently into engagement with the recess 25 in the steerin pin 6 bymeans of a pair of adjusting screws 26 fitted into the axle housing 18and are adjustable to press suitable springs 21 against the two ends ofthe damper plate 23. The springs may engage over spigots 26a formed inthe adjusting screws 26. By adjusting these screws 26 the front and rearpairs of wheels I may be adjusted for alignment and the freedom orotherwise of the bogies to turn on the steering pins 6 may be regulated.The inclination of the steering pin 6 will tend to bring the steeringinto each bogie comprising an axle housing which may swivel about aninclined steering pin, a transverse axle mounted in the housing andsupporting a pair of ground engaging wheels on suitable bearings, asteering damper plate fitted in a transverse slot in the housing andhaving a recess to fit around and against a flat on the steering pin,sprin means mounted in the housing and engaging the damper plate topress the recess therein against the flat on the steering pin and meansto adjust the spring pressure on the damper plate.

2. A skate according to claim 1 in which the chassis with its groundengaging wheels is detachably secured to the skate plate and means isprovided for readily, releasing it and for securing in its place achassis having an ice blade.

3. A skate comprising a skate plate with means for attaching it to theusers footwear, a longitudinally disposed chassis with means fordetachably securing it beneath the skate plate and road engaging wheelbogies at each end of the chassis, an inclined steering pin on whicheach bogie is mounted for dirigible movement and a steering dampercomprising a damper plate engaging in a slot in the bogie housing andslotted to engage a fiat on the steering pin, spring means to engage theouter ends of the damper plate and means to adjust the resilientpressure on the damper plate.

4. A skate according to claim 3 in which the chassis extendslongitudinally beneath the skate plate, forked lugs on the underside ofthe skate plate, squared parts on the chassis which. engage between theforks of these lugs, upwardly projecting pins on the chassis which passthrough the skate plate, resilient buiiers interposed between thechassis and the skate plate and clamping nuts on the pins to secure thechassis to the skate plate.
